0680cfc8dc Rename most instances of master to primary in tests.
This aligns better with general PostgreSQL usage and our own documentation (updated in 4bcef702).

Usage in the backup.manifest tests has not been updated since it might break the file format.

b5dd14e6f3 Make storage type more generic in the integration tests.
Rather than bS3 use strStorage which can indicate more than two storage types.

For the moment there are still only two storage types but this change is required before more can be added.

Add bzip2 compression support.
bzip2 is a widely available, high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), while being around twice as fast at compression and six times faster at decompression.

bzip2 is currently available on all supported platforms.

47aa765375 Add Zstandard compression support.
Zstandard is a fast lossless compression algorithm targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library.

Zstandard version >= 1.0 is required, which is generally only available on newer distributions.

731b862e6f Rename BackRestDoc Perl module to pgBackRestDoc.
This is consistent with the way BackRest and BackRest test were renamed way back in 18fd2523.

More modules will be moving to pgBackRestDoc soon so renaming now reduces churn later.

36d4ab9bff Move Perl modules out of lib directory.
This directory was once the home of the production Perl code but since f0ef73db this is no longer true.

Move the modules to test in most cases, except where the module is expected to be useful for the doc engine beyond the expected lifetime of the Perl test code (about a year if all goes well).

The exception is pgBackRest::Version which requires more work to migrate since it is used to track pgBackRest versions.

c279a00279 Add lz4 compression support.
LZ4 compresses data faster than gzip but at a lower ratio.  This can be a good tradeoff in certain scenarios.

Note that setting compress-type=lz4 will make new backups and archive incompatible (unrestorable) with prior versions of pgBackRest.

79cfd3aebf Remove LibC.
This was the interface between Perl and C introduced in 36a5349b but since f0ef73db has only been used by the Perl integration tests.  This is expensive code to maintain just for testing.

The main dependency was the interface to storage, no matter where it was located, e.g. S3.  Replace this with the new-introduced repo commands (d3c83453) that allow access to repo storage via the command line.

The other dependency was on various cfgOption* functions and CFGOPT_ constants that were convenient but not necessary.  Replace these with hard-coded strings in most places and create new constants for commonly used values.

Remove all auto-generated Perl code.  This means that the error list will no longer be maintained automatically so copy used errors to Common::Exception.pm.  This file will need to be maintained manually going forward but there is not likely to be much churn as the Perl integration tests are being retired.

Update test.pl and related code to remove LibC builds.

Ding, dong, LibC is dead.

438b957f9c Add infrastructure for multiple compression type support.
Add compress-type option and deprecate compress option. Since the compress option is boolean it won't work with multiple compression types. Add logic to cfgLoadUpdateOption() to update compress-type if it is not set directly. The compress option should no longer be referenced outside the cfgLoadUpdateOption() function.

Add common/compress/helper module to contain interface functions that work with multiple compression types. Code outside this module should no longer call specific compression drivers, though it may be OK to reference a specific compression type using the new interface (e.g., saving backup history files in gz format).

Unit tests only test compression using the gz format because other formats may not be available in all builds. It is the job of integration tests to exercise all compression types.

Additional compression types will be added in future commits.

02aa03d1a2 Remove obsolete methods in pgBackRest::Storage::Storage module.
All the methods in this module will need to be implemented via the command-line in order to get rid of LibC, so the first step is to reduce the code in the module as much as possible.

First remove storageDb() and use storageTest() instead.  Then create storageTest() using pgBackRestTest::Common::Storage which has no dependencies on LibC.  Now the only storage using the LibC interface is storageRepo().

Remove all link functions since those operations cannot be performed on a repo unless it is Posix, in which case the LibC interface is not needed.  Same for owner().

Remove pathSync() because syncs are not required in the tests.  No test data is reused after a crash.

Path create/exists functions should never be explicitly performed on a repo so remove those.  File exists can be implemented by calling info() instead.

Remove encryption detection functions which were only used by Backup/Archive::Info reconstruct() which are now obsolete.

Remove all filters except pgBackRest::Storage::Filter::CipherBlock since they are not being used.  That also means there are no filters returning results so remove all the result code.

Move hashSize() and pathAbsolute() into pgBackRest::Storage::Base where they can be shared between pgBackRest::Storage::Storage and pgBackRestTest::Common::Storage.

8b682b75d2 Allow mock integration tests for all VM types.
Previously the mock integration tests would be skipped for VMs other than the standard four used in CI.  Now VMs outside the standard four will run the same tests as VM4 (currently U18).

These tests are redundant now that we have full coverage in the unit tests are are not worth maintaining anymore.

4815752ccc Add Perl interface to C storage layer.
Maintaining the storage layer/drivers in two languages is burdensome.  Since the integration tests require the Perl storage layer/drivers we'll need them even after the core code is migrated to C.  Create an interface layer so the Perl code can be removed and new storage drivers/features introduced without adding Perl equivalents.

The goal is to move the integration tests to C so this interface will eventually be removed.  That being the case, the interface was designed for maximum compatibility to ease the transition.  The result looks a bit hacky but we'll improve it as needed until it can be retired.

b498188f01 Error on db history mismatch when expiring.
Amend commit 434cd832 to error when the db history in archive.info and backup.info do not match.

The Perl code would attempt to reconcile the history by matching on system id and version but we are not planning to migrate that code to C.  It's possible that there are users with mismatches but if so they should have been getting errors from info for the last six months.  It's easy enough to manually fix these files if there are any mismatches in the field.

86482c7db9 Reduce log level for all expect tests to detail.
The C code is designed to be efficient rather than deterministic at the debug log level.  As we move more testing from integration to unit tests it makes less sense to try and maintain the expect logs at this log level.

Most of the expect logs have already been moved to detail level but mock/all still had tests at debug level.  Change the logging defaults in the config file and remove as many references to log-level-console as possible.

3a05359087 Create test matrix for mock/stanza to increase coverage and reduce tests.
The same test configurations are run on all four test VMs, which seems a real waste of resources.

Vary the tests per VM to increase coverage while reducing the total number of tests. Be sure to include each major feature (remote, s3, encryption) in each VM at least once.

6d3e18b181 Reduce expect log level in mock/stanza tests.
The expect tests were originally a rough-and-ready type of unit test so monitoring changes in the expect log helped us detect changes in behavior.

Now the stanza code is heavily unit-tested so the detailed logs mainly cause churn and don't have any measurable benefit.

Reduce the log level to DETAIL to make the logs less verbose and volatile, yet still check user-facing log messages.

beae375330 Enable S3 storage for archive-get command in C.
The only change required was to remove the filter that prevented S3 storage from being used.  The archive-get command did not require any modification which demonstrates that the storage interface is working as intended.

The mock/archive/3 integration test was modified to run S3 storage locally to provide coverage for the new code paths while mock/stanza/3 was modified to run S3 storage remotely to provide coverage for the existing code paths.  This caused some churn in the expect logs but there was no change in behavior.

8a3425ec04 Automate generation of WAL and pg_control test files.
The existing static files would not work with 32-bit or big-endian systems so create functions to generate these files dynamically rather than creating a bunch of new static files.

6ef2167e97 Fixed an issue retrieving WAL for old database versions.
After a stanza-upgrade it should still be possible to restore backups from the previous version and perform recovery with archive-get. However, archive-get only checked the most recent db version/id and failed.

Also clean up some issues when the same db version/id appears multiple times in the history.
